The forms of speech by which the passions are expressed, are partly the same, and partly different from those, by which we express our thoughts. And first, generally all passions may be expressed “indicatively”; as “I love,” “I fear,” “I joy,” “I deliberate,” “I will,” “I command”: but some of them have particular expressions by themselves, which nevertheless are not affirmations, unless it be when they serve to make other inferences, besides that of the passion they proceed from. Deliberation is expressed “subjunctively”; which is a speech proper to signify suppositions, with their consequences: as, “if this be done, then this will follow”; and differs not from the language of reasoning, save that reasoning is in general words; but deliberation for the most part is of particulars. The language of desire, and aversion, is “imperative”; as “do this,” “forbear that”; which when the party is obliged to do, or forbear, is “command”; otherwise “prayer”; or else “counsel.” The language of vainglory, of indignation, pity and revengefulness, “optative”: but of the desire to know, there is a peculiar expression, called “interrogative”; as, “what is it,” “when shall it,” “how is it done,” and “why so?” other language of the passions I find none: for cursing, swearing, reviling, and the like, do not signify as speech; but as the actions of a tongue accustomed.
